STORAGE- BATTERY.

SPECIFICATION forming part of Letters Patent No. 386,580. dated July 24. 1888.

Application flied Fermi-m. ises. Serial No. mam. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN A. Enos, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Storage-Batteries,of which the'follmving is a specification;

My invention relates to storage-batteries; and it consists in the peculiar construct-ion and arrangement of -the elements, which are mounted upon a rotary shaft, soas to revolve,

as will be hereinafter fully described.

Figure 1 is a side view of the battery,partly in section. Fig. 2 is a verticaLcross-section of the battery. Fig. 3 is a vertical longitudi- Fig. 4.- is a horizontal longitudinal section of a middle cell. Fig. 5 is a partial side view of the revolving battery elements. Fig. '6 is a perspective view showing the connections of the positive and 2c negative spiral strips at the hub of the-revolving shaft. Fig. 7 is a detail of one of tie insulating-blocks.

In the drawings, A A represent the two portions of the outer casing of the battery, 2 which are made in semi-cylindrical shape with flanges, which are bolted together at a. The.

lower portion, A, of the case is cast with longitudinal supporting ribs or flanges A, which slide u'pon grooved guide rails orways A, which are to be attached to the car or other structure to which the battery is to be applied. This construction facilitates the sliding in and out of the batteries and holds them firmly against dislodgment when so slid in.

Both the upper and lower sections of the case are provided with separating-partitions B --and B, which form a number of circular cells arranged side'by side. The outer casing is made of iron and the inner surface is lined 40 with hard rubber. B is a longitudinal shaft 1 rennin through all of these cells and carried in bear ng s in the ends and in the partitions. This shaft is also covered with a tube, E, of hard rubberr Itigidly fixed to this shaft in each one of the cells is a set of battery elements, each of which is composed of two spirally-wound metallic ribbons, CD, of lead,

which are wound in parallel position to each other without touching, and extend in disk form from the center shaft to nearly the inner periphery of the cell. The'se ribbons are maintained apart from each other by hard-rubber spacing blocks H and radiating arms .11. These latter are made fast to and revolve with the. shall, and through them screws 8 pass into the spacing-blocks. These spaci llg-blOOkB (see Fig. 7) have recessed sides or flanged ends, so

that when the ribbons are in place the latter;

rest in the recess between two adjacent blocks, while the flanges of the blocks abut against each other.

One of the ribbons, O,is electro-negative and the other e1ectro-positive, and they have detachcd insulated connections at the shaft, as shown in Fig. 6, in which ribbon G is attached to a diagonally-cut'metal sleeve, 0. and ribbon D to a. similarly-cut sleeve, D,,a hardrubber washer, G, being located between them. The outer ends of these metal sleeves extend past the radiating arms F and give a bearing for the brushes or current-conductors J J, Fig. 4 which latter are insulated from each other, but are connected in series (J of one cell with J of the next) through wires b, passing through holes in the partitions B. At the ends of the batteries are the terminal wires 0 and h.

In the lower portion of the case a dilute mixture of water and sulphuric acid is placed, and the battery elements 0 D are filled or equipped with the usual materials'required in a storage-battery.

At the end of the battery and arranged to turn the shaft 13 is a clock-work, W, which, by giving a slow rotation to the shaft B, constantly brings new portions of the battery elements into the solution, thus equalizing the action and rendering the current more uniform. In order to'prcvent the spiral ribbons from taking up the solution and carrying'itto the center shaft, where it would soon destroy the insulation, ibis necessary'to rotate the shaft in one direction only, and that is as shown by the-arrow in Fig. 2.

The invention may be applied with equal advantage in the construction of primary galvanic batteries Having thus described my invention, what 5 I claim as new is- 1. The battery-case herein 'described, eon-. sisting of two semicylindrical sections, one'of which is provided with longitudinal guideflange's or supporting-ribs A A, adapted to 'iornn upon ways, substantially asishown'and v described.

2.. The combination, with the battery-case and a horizontal shaft arranged to rotate there:

' ,in, of two spirally-wound metal ribbons form- 15 ing the 'two (elements, the said ribbons being insulated from each other and attached to the shaft, and radial'arms for supporting the same, substantially asshown and described.

"3. The connbinat'i'on, with the shaft B, havinginsulating-tnbeE; ofthediagonally-cutand 2o insulated sleeves C D',the metal ribbons CD,

attached thereto, and the radial arms F-F, substantially'as shown and described.
